【摘要】：分析了2015年第173~175d太阳活动对电离层以及地磁场的影响以及磁暴期间电离层延迟高阶项对观测值、静态PPP的影响。结果表明,受173d爆发的日冕物质抛射和冕洞高速流的共同影响,174d地磁持续扰动,达到大磁暴水平;L1、L2的二阶项延迟最大值分别达到20 mm、40 mm,三阶项延迟为2 mm、5mm;电离层高阶项延迟对PPP的N方向的影响最为显著,最大值达到了7.1mm,且呈向南偏移的趋势,对U、E方向影响的最大值可达4.6mm,但没有一致偏移的规律。
[Abstract]:The effects of solar activity on the ionosphere and geomagnetic field at 173d 175d, 2015, and the effects of the higher-order term of ionospheric delay on the observed values and static PPP during magnetic storms are analyzed. The results show that the continuous geomagnetic disturbance of 174d is affected by the coronal mass ejection and the high velocity flow in the coronal hole. The maximum of the second term delay and the third order term delay are 20 mm / 40 mm and 2 mm / 5 mm respectively, and the ionospheric high order term delay has the most significant effect on the N direction of PPP, the maximum value is 7.1 mm, and the trend is southward. The maximum value of the influence on the direction of UGU E can reach 4.6 mm, but there is no uniform deviation rule.
